Reflection Data Acquisition, land or sea), depth to be probed, and inhabitance, etc. Commonly used seismic sources in land areas are explosives, except in populated areas with a large density of dwellings. For seismic surveys in marine areas, a source like ‘sparker’ or ‘air-gun’ is used.

Attributes of Routine Reflection Processing and Pitfalls,ot only precise structural interpretations are possible but valuable conclusions may be deduced about lithology, fluid content, porosity, stratification, depositional processes and environments, sediment transport direction and geological evolution, etc.

Anisotropy Models of Sedimentary Sections and Characteristics of Wave Propagation,stals. A crystal’s properties are governed by the periodic structure of its atoms. The study of anisotropic behavior of crystals has greatly helped understanding seismic anisotropy of sedimentary rocks and fractured zones. With this perspective, some salient points of anisotropy in crystals are intr

Raypath, Wavefront Curvature, Normal Moveout Velocity (VNMO) and Subsurface Medium Properties, wave energy is partitioned; a part of the energy returns back as a reflected wave and another part is transmitted as a refracted wave. Our interest in seismic (reflection) prospecting centers on the reflected wave. The reflected and transmitted waves propagate on wave fronts or wave surfaces. A di

,Analysis of t2−x2 Relations,t a more informative way is to examine (t−x) arrivals in the (t.−x.) plane. The hyperbola in the (t−x) plane gets transformed into a straight line in the (t.−x.) plane. The slope of the ‘t.−x.’ graph is used to find the stacking velocity. By equating stacking velocity to RMS velocity (VRMS), interva
